Surendranath, Lead @ Bank of America going to give live demo on Configuration as a Service (CaaS). This service offers configurations of an application to be saved, read, loaded, refreshed over an REST API call. It uses MongoDB as a repo source to store configurations. It eliminates the need for individual services to host their config files within the project there by offering more security. The custom configurations for a service can be refreshed on the fly with 0 downtime to the application.
